On public-script-coord, Boris Zbarsky showed an example [1] where a

global object it was attached to (because the WindowProxy has changed of
underlying window object).
No, nothing of the sort. The example shows it _present_ on the global
(the third alert in my example) but missing from the WindowProxy
(fourth alert).
I'm comparing the second and fourth alert (that's not what the example
was created to show, but that's what it shows too). In the second alert,
there is the 'foo' property and it is non-configurable as per the spec,
because you var-declared it. In the 4th alert, the property has
magically disappeared.
